GEORGE F. BEEBE, OF HORNELLSVILLE, NEXV YORK.

PUMP.

SPECIFICATION forming part of Letters Patent No. 279,214, dated June 12, 1883.

Application filed May 10, 1883. (No model.)

-To all whom it may concern:

Be it known that I, GEO. F. BEEBE, a citizen of the United States, residing at Hornellsville, in the county of Steuben and State of New York, have invented certain new and use ful Improvements in Pumps, of which the following is a specification, reference being had to theaccompanying drawings.

My invention consists of certain improvements in pumps, and particularly in a new check-valve, which will be fully understood by the accompanying description and claims.

The chief objects I have in view are to produce a combined lifting and force pump without stuffing-box or air-chamber or the use of leather or of bolts, (except in connection with thehandle and lower piston,) and small enough to be put into a bored well of four inches in diameter, and capable of lifting or forcing water to any desired height, and not liable to injury from frost or hot water.

In the accompanying drawings, Figure l is a side View of my improved pump. Fig. 2 is a vertical section through the check-valve and lower end of the main cylinder. Fig. 3 is a vertical central section of the pump with the valves in position for a force-pump. Fig. 4 shows the upper valve lowered into the large cylinder D, thus making a lift-pump. Fig. 5 shows the piston-rod and both pistons.

The main cylinder A of my pump is made very long, so that the piston B (which is adjustable) may be worked with full stroke either in the upper or the lower part. Above the spout is a second cylinder, 0, with a secondary piston, E, working therein. A third cylinder, D, is made of greater diameter than the cylinder 0, in order to allow the secondary piston E to play loosely therein when the pump is used as a lifting-pump. The main cylinderA is made from a section of wrought-iron pipe, both ends being screw-threaded and provided with cast-iron caps or and a. The secondary cylinder 0 is also made from a section of wrought-iron pipe screwed into the upper end of the third cylinder, D, which is cast in the same piece with the spout F.

The attachment G is cast with a socket to receive the adjusting-rod H of the handle I, said attachment being slipped loosely upon the upper end of cylinder 0, and secured in place by a cap, K, screwed upon pipe 0. The

height of the pistons in the pump is regulated by adjustingthe rod H up or down. The upward motion of the rod is limited by the stop or shoulder h, and it is securedin any desired position by the screw 9.

The lower cap, a, of the main cylinder is cast with a dish-shaped valve-seat, M, so as tov clear itself of gravel and sand, which are easily washed down through the central passage in said seat. The check-valve is fitted to this dish-shaped valve-seat by means of the flexible and vibrating rubber disk M and the inflexible disk L, which is made convex on the under side, so as to fit the form of the valve-seat and bring the rubber disk home thereon by the simple weight of the clieclevalve.

The valve-stem Nis provided with a guide, 0, which drops into place, being held by notches T, cast in the cap a, and the lower end of this stem is screwed into the lower guide, P, which is cast with radial wings or bearings 12, fitting the passage in the cap a, which hold the check-valve in the center of the valve-seat and prevent the possibility of the same resting too much on one side and allowing a leak.

In casting the spout a nipple, Q, is inserted into the mold 'for the purpose of attaching the hose R.

By means of the attachment G the handle may be turned into any position in relation to the spout.

WVhen the handle and pistons are raised, as shown inFig. 3, the main or lower piston, B, works in the upper part of the cylinder A, and the upper piston, E, works in the upper cylinder, C, so that the pump acts as a forcepump, the lower piston acting as the two pistons rise, and the upper piston acting as both pistons go down, thus giving a continuous and powerful stream of water 5 but when the handle and both pistons are lowered, as shown in Fig. 4, the upper piston comes down into the third cylinder, D, and plays loosely in this enlarged cylinder, nearly opposite the spout, thus making a simple lift-pump.

The piston-rod S and the pipe above or be low the main cylinder may be made longer or shorter, as desired, for wells of different depths. A very important feature of my check-valve is the vibration of the flexible rubber disk M, which bends to fit the valve-seat as the checkvalve drops into place, and straightens out flat,

as shown in Fig. 3, when the valve rises. This motion of the disk of rubber in relation to the convex metallic disk L insures the clearing of the valve from mud or sand.

By the use of two guides my check-valve will work without binding when the pump and valve-stem are placed horizontally, and the upper guide, 0, limits the upward motion or stroke of the valve.

Hz ving described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the flexible vibrating disk M with the inflexible disk L, having a convex side, and the dish-shaped valve-seat," for the purposes set forth.
